T 0 (LZZ whont it nwu concern:

Be it known that I, JAMES L. FRAZIER, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Splicing-Sockets forCables; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to sockets for splicing ropes and cables.

The object of the invention is to provide means for connecting orsplicing the ends of cables.

A further object of my invention is to provide a device for splicingpower-transmitting cables which have been broken, so that said cables,which sometimes have to be discarded, can be repaired in a very fewminutes, thereby losing but little time. This is of especial value inlarge mines, where loss of time means a loss of much money. Where it ispossible to repair broken cables, provided they are of suflicientlength, the ends are usually untwisted for considerable distance and apiece of cable is spliced in; but such an operation consumes the greaterpart of a day.

Another object of the invention is to provide a coupling for a cable ofpeculiar form that will pass readily through small openings and oversmall pulleys without catching or causing trouble.

In the accompanying drawings, Figure 1 is a side view of mysplicing-socket combination, showing one of the sockets partly unscrewedand the other one partly broken away to show interior construction. Fig.2 is a top view, partly in section, of parts of the sockets, showing aconnecting-link, which is also shown in Fig. 1.

A A indicate the bodies of two socket portions of oval form, both havingtheir ends cut squarely off in a plane at right angles to their axes.The said members A A have hollow interiors at B, the recess in eachbeing gradually enlarged from their outer ends inward, as shown insection in Fig. 2. In the large end of the socket member is a threadedopening 0, which receives a threaded member D, forming part of an eye E.This eye is provided with an aperture F, through which passes a ring G.

The entire device, it will be seen, comprises five partsnamely, the twosocket members A A, the eyes E, having the threaded stems D, and thering G. It is my design to connect both the said eyes E together bymeans of the ring, the latter being firmly welded together at its endsto make an unbreakable link connection.

In connecting the broken ends of a cable it is only necessary to untwistthe ends for an inch or two after passing said end through the socket Afrom its small end and turn the strands back upon themselves. This makesan enlarged head on the cables end, which when drawn back into therecess B wedges therein, and the end of the cable cannot be pulled outthrough the contracted end. M olten lead may be poured in around thehead,

thereby making a solid block but the former a method is preferable,since if the metal is not ready for use the connection can be made morequickly without it. After both ends of the cables are thus treated andseated in the recesses B the eyes are screwed into place. In order toaccomplish the latter operation in the easiest and most effectivemanner, the

stems D are provided with right and left hand threadsthat is to say, oneof them is given a right-hand and the other a left-hand threadas shownin Fig. 1. Now by bringing the portions A A toward one another andplacing the eyes E between them and entering their threaded stems D intothe threaded openings O the threads are made to engage, and by turningthe eyes in the proper direction the sockets are drawn tight up to theshoulders of the eyes. The connection is now complete except forentering a pin H through each socket and its complementary stem D andriveting both ends of the said pins, as shown in Fig. 1, at the right,it being understood that a hole J has previously been drilled throughthe parts for the reception of the pins, so that all will be inreadiness for the splicing operation described.

It will be noted that the members E being flattened and tapered to asmall end, as shown in Fig. 2, admit of the use of quite a small link,but a strong one, whose measurement is but little larger than thegreatest diameter of the parts A, so that it will pass over a pulley orthrough an opening made to accommodate the said parts A.

The advantages in a device of this kind are at once apparent, and mineis especially convenient by reason of its construction and arrangementof parts.

I claim- In a coupling of the class described the combination of a ropemember tapered from one end to the other and having a partiallongitudinal tapering bore the surface of which is substantiallyparallel With the tapering exterior of the member, the cable ends withinsaid bore, said member at its small end. being substantially the samediameter as the cable, there being a second straight bore Within thelarger end of the said rope member opening into the tapering bore and ofconsiderably smaller diameter than the latter bore and provided withscrew-threads, a link-carrying member having a body of the full diameterof the rope member and having a threaded extremity of reduced diameterto screw into the threaded bore of the said rope member,

said body being flattened. and tapered at two diametrically oppositesides beginning immediately at the first member as shown, there being ahole through the flat sides to form a closed eye, a second combined ropemember and link carrying member identical with those described, and aclosed link for connecting the said link carrying members, the shortestdiameter of the link having a diameter substantially equal to thegreatest diameter of the coupling members, and a pin. extending througheach extremity of the linkcarrying members and the rope members asshown.

In testimony whereof I aHiX my signature in presence of two Witnesses.

JAMES L. FRAZIER.
